php - How to change the environment in Laravel 5.1? -

-

what understand working of environments in laravel have different environments different, environments. so, if running app locally have .env.local file. if testing or on production, use .env.testing or .env.production. (correct me if wrong.)
default .env file can edit. can tell me workflow of changing environments in laravel. tried documentation couldn't it. please me.

when install laravel 5.1 2 files .env , .env.example if want work locally set :

app_env=local app_debug=true

in prod set

app_env=production app_debug=false

an error message in debug mode

enter image description here

an error message production mode

enter image description here

note: have 2 .env files .env , .env.example .. can create 1 name .env.production keep in mind in order configuration loaded must rename file .env

edit : in case still working in local , need database test, can create file in total have 3 .env files :

.env.production .env.local1 .env.local2

whenever want switch configuration rename desired file .env

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
